Stranoch & Chirmorie


Scottish Power Transmission plc (SPT) as the transmission license holder on behalf of Scottish Power Energy Networks Holdings Ltd (SPEN) has submitted three applications to the Scottish Government for Section 37 consent and deemed planning permission under section 57(2) of the Town and Country Planning (Scotland) Act 1997  for the overhead line connections and associated access arrangements necessary to connect both Stranoch wind farm and Chirmorie wind farm to Mark Hill substation across the local authority areas of South Ayrshire and Dumfries and Galloway areas.

The proposal development

The supporting environmental appraisal report provides information to support all three applications and is also provided in order to meet the applicant’s obligations to preserve amenity and mitigate environmental effects under Schedule 9 of the Electricity Act 1989.

The overhead line applications include:

  • One application to cover the section of the proposed development from Stranoch wind farm substation to pole 119;
  • One application to cover the section of the proposed development from Chirmorie wind farm substation to pole 119;
  • One application to cover the section of the proposed development from pole 119 to pole 001.

The proposed development also includes a section of underground cable for the final approach into Mark Hill substation which constitutes permitted development under Class 40 of the Town and Country Planning (General Permitted Development) (Scotland) Order 1992 (as amended). This underground cable section would not be subject to assessment as part of the S.37 consent applications.

The location of both the consented Stranoch and Chirmorie wind farms and the Mark Hill substation, as well as the proposed overhead line is shown in the attached figures.
